In the Name of Allah, the Most Gracious, the Most Merciful.
ن
(Nun), is like Allah's saying,
ص
(Sad), and Allah's saying,
ق
(Qaf), and similar to them from the individual letters that appear at the beginning of Qur'anic chapters. This has been dis- cussed at length previously and there is no need to repeat it here.
The Explanation of the Pen Concerning
Allah's statement,
وَالْقَلَمِ
(By the pen) The apparent meaning is that this refers to the actual pen that is used to write. This is like Allah's saying,
(Read! And your Lord is the Most Generous. Who has taught by the pen. He has taught man that which he knew not.) (96:3-5) Therefore, this statement is Allah's swearing and alerting His creatures to what He has favored them with by teaching them the skill of writing, through which knowledge is attained. Thus, Allah continues by saying,
فَسَتُبْصِرُ وَيُبْصِرُونَ بِأَييِّكُمُ الْمَفْتُونُ (So, you will see, and they will see which of you is demented....68:5-6]. The word maftun, in this context, means 'demented'. In the preceding verses, the Holy Prophet ', was accused of being an insane and demented. This verse turns tables upon the accusers of the Holy Prophet , and making a prophecy, tells them in challenging words that time will show whether it was he or they who suffered from insanity, or whether his claim to be Allah's Messenger ﷺ was the outpouring of heated brain, or whether they themselves were so demented as not to read the signs of time, and thus refuse to believe in him. These were the unfortunate, wretched ones who did not see the light of Truth and were thus disgraced and defeated in this world. But, on the other hand, there were thousands of other lucky ones who, at first did not see the light of Truth and denounced him as demented, soon saw the light and embraced the Faith of Islam. They took the love and obedience of the Holy Prophet as the capital asset of success, prosperity and happiness.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 4–15
Having a sublime character means rising above the standard of others’ behaviour. It should not be the believer’s way to deal badly with those who are not good to him, while giving fair treatment to those who are good to him. On the contrary, he should do good to everybody, even though others may not do the same for him. The character of the Prophet was of the latter type, which proves that he was a man of principle. He was not a product of circumstances, but of his own high principles. His sublime character was consistent with his claim to be a prophet.
